1. In the 20th century, the famous television show Popeye encouraged its audience to eat spinach. The producers of the show said spinach had as much iron as red meat. Lo and behold, the producers got these results from an 1870 German report that had misplaced its decimal point. Meaning spinach actually has 10 times less iron than red meat . Spinach ain’t all that good for you!

2. In 1962, NASA launched the probe named Mariner 1. However, it had a system failure and crashed due to one little typo. Some jackass forgot to put the overbar over the letter “R.” Yep, seems like little typos like these are such a big freaking deal due to rocket science being a harsh mistress.
